IIVPROVEIVIiENT IN AUTOMTIC BO'lLER-FEEDERS.

To all whom t 'may concern:

Be it known that I, WM. MOORE, ofl Kokomo, in the county of Howard andState of Indiana, have invented a new and useful lmprovement inAutomatic Steam-Boiler Feeders; and I do hereby declare the following isa full, clear, and exact description of the same, reference bein ghad tothe accompanying drawings, and to the letters of reference markedthereon, and which make part of this specifi! cation. n

Like letters in each of the 'figures denote the same parts.

Figure 1 is a top view. Fig. 2 is a front view. Fig. 3 is asection,showing supply and waste pipes, also how the partition may bemade movable, 85e.

The object. of my invention is to supply a sufficient quantity of waterto the boiler at all times, as well as to indicate the quantity in theboiler, thereby aifordin g a sure precaution against the losses anddanger to life Iconsequent upon explosion of steam-boilers, especiallythose used in saw-mills and for similar purposes.

Ihe nature of my invention consists in attaching a swinging nozzle tothe supply-pipe, and regulating the saine by means of a oat and levers,which are so arranged that when the water is lower in the boiler agreaterquantity will be supplied by the nozzle being brought morel,directly over the mouth ofthe pipe which supplies water to theheating-chest, and which chest is connected directly to the force-pumpwhich supplies the boiler. As the water is higher in the boiler a lessquantity will be supplied, in consequence of said nozzle receding orcoming more directly over the waste-pipe, the wastepipe and supply-pipebeing separated at top only by the thickness of a piece of tin.

`To enable others skilled in the art to make and use this feeder, I willproceed to describe the same by means of the drawings.

A is a boiler of any ordinary construction, perforated in either end (orin the side, if desirable) by a hole of suitable dimensions, into whichI insert the shaft M, Fig. l, which is rendered steam-tight by means ofa stufiingbox. On the inner end of said shaft is attached the tloat X,Fig. 2, having a suitable lever to cause it to rise and fall with thesurface of the Water in the boiler. Said shaftY extends out from theboiler over the support It, which has a partial iiange on the upperside, against which the outer end ofthe shaft Works on a pivot at L,Fig. 2.

J is a lever attached to the shaft for the purpose of balancing thefloat X. T is a cam working against a spring', (or the same effect maybe produced by the usual leverand-joint arrangement,) which gives analarm by means of the Whistle S when from any cause the force-pump hasfailed to supply a sufticiency of water to the boiler. U is au armconnected to another arm, YV, by means of a togglejoint. The arm U isconnected yto the shaft It by a fixed joint. The arm W is connected tothe swinging' nozzle a, and by the rising and falling of the iioat X itwill be readily seen the nozzle Will be regulated over the supplypipe Gror waste-pipe E as a greater or less quantity of water is needed, and soaccurately may it be'graduated that it is impossible for the water tovary so as to cause any danger of explosion or any perceptibleirregularity in the generation of steam.

It, Fig. l, is the force-pump, with its pipes for receiving anddischarging water. I is a hot-water chest, which is heated bywastesteam, to which is attached a waste-Water pipe, P, and a wastesteampipe, E.

I would here state that instead of the swinging nozzle an indiawrubbertube may be used, or the tube V may be Xed or stationary7 and the supplyand waste pipes may be hung or iiXed to move to and fro under said tube;or in some cases it might be more convenient to have all three of thetubes fixed and the partition movable, so as to direct the water intothe supply or waste pipe, as necessity required.

The principal difficulty I aim to overcome is that experienced in theuse of automatic stop-cocks and other means heretofore in use insupplying water t6 steam-boilers, by which the supply becomes irregularand sometimes ceasing entirely in consequence of the parts becomingiilled up by sediment or by the stopcocks becoming inoperativeA bycorrosion and other causes. In my invention these difficulties are meantto be overcome, for however muddy the Water it has a free passage fromthe size of the tube used, and its ceasing to flow is readilydiscernible at all times.

Another advantage of my automatic boi1er feeder consists in the mannerof arranging the shaft so as to overcome a great amount of y friction,and at the same time attaching a Whistle, so as to give an alarm if fromany cause the water should becomelow in the boiler.

In my arrangement the only friction to overcome is that in thestuffing-box and at the pivot, both of which can be easily lubricated.The float being thus rendered very reliable,

the whistle can therefore be depended upon,

1. The swinging nozzle or its equivalent, y

constructed and arranged substantially as described.

2. The combination of the swinging nozzle with the shaft B, arranged Vinthe support R,

with the pivot L, substantially as described,`

and for the purpose set forth.

3. The combination and arrangement of the nozzle a, shaftB, and WhistleS, all constructed and arranged as and for the purposes set forth.

In testimony whereof l have signed my name to this specification. l lWILLlAM MOORE. Witnesses:
